Struct DragDropDevice 

Source 
pub struct DragDropDevice { /* private fields */ }
Expand description

The input device that turns the raw drag events of the platform into the routed drag-and-drop events of DragDrop.

This is an implementation detail of the platform backends.

Implementations§

Source§

impl DragDropDevice

Source

pub fn instance() -> Rc<DragDropDevice>

The drag-and-drop device of the current thread.

Trait Implementations§

Source§

impl IDragDropDevice for DragDropDevice

Source§

impl IInputDevice for DragDropDevice

Source§

fn process_raw_event(&self, e: &dyn IRawInputEventArgs)

Processes raw event. Is called after preprocessing by the input manager.
Source§

fn as_any(&self) -> &dyn Any

The device as Any, for downcasting to the concrete device.
Source§

fn as_pointer_device(&self) -> Option<&dyn IPointerDevice>
